TO ALL WHOM IT MAY CONCERN: i s

Be it known that I, ALBERT DANIELS, of the city of Hartford, in the-county of Hartford, and State of Connecticut, have invented certain new and useful Improvements in Eye-Glasses and I do hereby declare the b fiollowing to be a full, clear, and exact description of the same, reference being hadto the annexed drawing,

making part of this specification, in which Figure 1 is a front view of a pair of eye-glasses, withniy improvement applied thereto.

Figure 2 is an edge view of the same, and

Figure 3 is a part of the invention to be hereinafter more fully explained.

The object of my invention is to increase the energy and adjustability of the nose-spring of the glass, without increasing its weight or thickness, and without decreasing its length, capacity, or pliahility.

To accomplish this object I make the spring in the form substantially as shoun, andapply it to the frame of the glass between the flanges (l d, through Whicha scrw is passed to secure the glassin the frame, and which also secures the ends of the spring hy'which the two glass-frames are united. 7

New, this spring, simply made and attached byithe ends in this way to the glass-frame, would not have suflicient energy to hold it upon the nose with firmness, unless it were made so stifl' and clumsy as to be otherwise impracticable. But by'making and applying to the glass-frames the studs 0 c, with their outer ends made to pass through openings in the spring, and which studs are fitted with collars to bear against the inside thereof, the 'energyof the spring will be maintained when the glasses are drawn apart, and the greatest contractingpressure will be exerted nearest the top of the nose, by which the glass will be held from falling over, that is to say, dropping away from the eyes. v

By this construction and arrangement of spring, the cushion or bearing-pieces ie here, instead of being applied to the glass-frame, as in the ordinary method, applied to thetspring itself, which,"i n this case, bears on the nose.

Having now described the nature and extent of my invention, Bel-aim as new, and desire to secure by Letters Patent- I i 1. The spring a, constructed and applied to the frames of the eye-glasses, substantially as described.

2. The studs 0 0, made and.\applied to the frame of the eye-glass, and the spring, substantially as described,

for the purpose specified.
